4.4.2 Grounding
Use as short as possible cable to the grounding point on the switchboard.
Use cable min. 2,5 mm
2
.
The “-“terminal of the battery has to be properly grounded.
4.4.3 Power Supply
Use min. power supply cable of 4mm
2
.
Maximum continuous DC Power supplyvoltage is 36 V DC. Maximum short term allowable power supply
voltage is 39 V DC. The ECON-4’s power supply terminals are protected against large pulse power
disturbances. When there is a potential risk of the controller being subjected to conditions outside its
capabilities, an outside protection device should be used.
Power Supply Fusing
An eight-amp fuse should be connected in-line with the battery positive terminal to the controller and modules.
ECON-4 should never be connected directly to the starting battery.
Recommended fuse is slow type – T8A.
4.4.4 Binary inputs
Binary inputs have internal load resistor 4.4 kΩ connected to the battery plus.
